Since the conversion from NV12 to RGB on the CPU does not scale for larger photo/video resolutions, this patch uses a different approach. It uses the low-level screen API to grab screenshots of the native viewfinder window and provides them as QImage to the QAbstractVideoSurface. Even for large resolutions this is quite performant.
